That's a lie. The first report of them was in the
2007-01-21 test:
This is MediaWiki version 1.10alpha (r19546).
<snip>
2 new FAILING test(s) :(
* URL-encoding in URL functions (single parameter)
* URL-encoding in URL functions (multiple parameters)
So, what happened?
They never passed the test, but were failing since someone added them.
So... no, it's correct, isn't it?
